Description

Use case: http://help.opscode.com/discussions/questions/155-package-versions-in-node-attributes

"I'm running chef-client on Debian Lenny and have run the monit cookbook from the Opscode site. Unfortunately monit fails to start because Lenny only has version 4 and the template includes a "with start delay" option that only works with version 5. I'd like to do the right thing and wrap that in a conditional so that it's only included with version 5 but how do I know which version has been installed?"

We've discussed this before, and it would be nice to do something like retrieving the @current_resource.version for comparison.

Well, you could do something like:

r = package("foo") do 
  action :nothing
end

provider = Chef::Platform.provider_for_resource(r)
provider.load_current_resource

At which point you could query the values in provider.current_resource

I'm not sure about the right way to make that easy to do.
